FFMS2000 - The experimental future of FFMS2

[Myrsloik]

Hint: look at the known issues

[stax76]

I've reported this some years ago, my workaround:

            Dim miFPS = MediaInfo.GetFrameRate(p.FirstOriginalSourceFile)
            Dim avsFPS = p.SourceScript.GetFramerate

            If (CInt(miFPS) * 2) = CInt(avsFPS) Then
                Dim src = p.Script.GetFilter("Source")
                src.Script = src.Script + BR + "SelectEven().AssumeFPS(" & miFPS.ToInvariantString + ")"
                p.SourceScript.Synchronize()
            End If

Yes I do the same if mediainfo reports Separated Fields.

I wonder if that relates to the problem with enabling "rffmode" I've been experiencing.

I was fiddling around with the old FFMpegsource2 script (changing the function name to avoid conflicts) in order to enable audio by default, and I also set rffmode=1 as the default, but I discovered for progressive h264 it causes ffms2/ffms2000 to output half the source frame rate. For the sources I tested, Info() said the frame rate was 24000/2002 instead of 24000/1001 (with one exception where it reported 1.#inf (1/0) as the frame rate).
rffmode=0 fixed the problem.

While I'm here, although I probably don't care anyway, was the utf8=true/false argument removed from this version of ffindex/ffms2 for a reason? Just curious...

Cheers.

Yes, it was removed.

Any new test versions? The test 6 is approaching 7 months old and I see there have been multiple commits

I guess I'll make one in a bit. Should have lots of interesting new bugs to find as well by now...

[burfadel]

Happy to test !

[stax76]

Me too, especially file extensions h264, h265 and ts.

I have been using FFMS2000 in VapourSynth until I found out recently that it is not reliable for MKV sources.
Luckily, L-SMASH replacement proved to be 100% deterministic so that's what I'm going to use further.

[Atak_Snajpera]

The only huge problem for me with newer versions of FFMS is broken seeking on VC-1 (each frame is detected as keyframe?!)

[Myrsloik]

New build

[Atak_Snajpera]

Great! This version fixes crashing on some .aac audio files!

[burfadel]

Has worked so far here great as well!

Hi to all,
I am new here, but I have used avisynth for a couple of years now and coded some filters for it.
So in the past it was possible to load DPX image files (10Bit per channel) into avisynth via FFImageSource, that doesn’t work anymore with FFMS2000 and avisynth+.
I have tried to load them via FFVideoSource and that works, but the output is RGB32 instead of RGBP10 or other higher bit depth formats.
Also FFMS2000 seems not to support DNG files.
Is it possible to find some solutions for this problems?

Loading dpx should work. Can I have a simple file? Which is the most recent FFMS2 version where it worked?

Did DNG ever work in any FFMS2 version?

[AKBabel]

I have tried to open the DPX files directly in VirtualDub Mod, it seems to work, they are interpreted as RGBA64.
If I encode them as ffv1 in mkv container, I can load that mkv into VirtualDub, same result RGBA64.
But when I open the DPX files through FFMS2000 they are interpreted as RGB32.
Here is a file: https://www.file-upload.net/download...74533.DPX.html

I'll try to found out, which version it was, that could open them via FFImageSource().

No, DNG was never supported by FFmpeg. I found that out recently.
I still hope that it may happen too.

I have checked.
The version where FFImageSource could open DPX is 2.17.0.0 (obviously it returns RGB32).
When trying to open DPX with FFImageSource from FFMS2000, it returns the Error:
FFVideoSource does not have a named argument ''utf8''

You didn't update ffms2.avsi. The utf8 argument was removed.
